IMPROVBMENT 1N WASHING-MACHINES.

The Schedule referred to in these Letters Patent and making part of the same.

To all 'whom it may conce/rn Be it known that I, C. A. OALAwAY, of Madison, in the county of Lake, and State of Ohio, have invented a new and useful Improvement in Washing- Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, -which will enable others skilled in the art to make and use the same, reference being had to ther accompanying drawings, forming part of this specification.

This invention relates to improvements in washingmachines, whereby it is designed to .improve the eiiiciency of the same. i

The invention consists in an improved` construction and arrangement of al concaved grooved bed in the bottom of a case or tub, apair of rollers pivoted to an oscillating frame, anda treadle-device for varying the pressure of the oscillatingrollers upon the bed or the clothes thereon, all as hereinafter more fully-specified.

Figure 1 represents a transversev section of my. improved machine, and 'v Figure 2 represents a longitudinal sectional elevation of the same.

Similar letters of reference indicate corresponding parts. Y

A represents the case or tub, which is preferably of rectangular form.

B represents a concave rubbing-bed, 'composed of grooved bars secured to concave supports 0,'at some distance apart, so that spaces 'will be provided'for a -free circulation of the water between the bars.

D represents a -pairrof rollers, journalledin end bearings E, pivoted centrally ,to suspending-bars F, :fixed to a roller, G, which is journalled in the upper ends of vertical-sliding ysupports H, pivoted at the bottomon the journalled endsvof a spring, -I, which is 'Patentsupported on a foottreadle, K, pivotcd at L to the frame of the machine, and projecting in front of the machine at M. i

lhe arms F are provided with o ne or more handles,

N, whereby they are oscillated to produce the rubbing? on the clothes, which are placed on the concave hed B, under the rollers D. These rollers being considerably separated,cause an intense action of the water between them, thereby increasing the eiiect on the clothes. l

The concave bed B is made'removable, to facilitate -cleaning out the -tub' or case, and the arms F are so arranged, relatively to the height of the case, and to the verticallymoving supports H, that when the latter are raised up as high as they may be by the treadle, the rollers may be swung upward out of the tub, the said supports being turned out of the vertical line, for which slots are provided in the supports, so that they will turn over the "curved guides O, which hold them up, to permit theI removal of the rollers, and which also serve, together with the guides P, to hold the
